@MikeMahoney218@coolbutuseless@yutannihilation NOTEs can definitely trigger emails from CRAN, and also package archivals from CRAN, this happens all the time. (In fact CRAN might request an update even if your package check is clean.)
OTOH there is nothing to do until they do email you, sometimes they change their minds, or sometimes they only enforce new rules for new submissions.
For the case at hand my guess is that they will enforce it, and I am updating my packages. Only a guess...
